Method

Cut the fat from the hock and put the hock and fat into a huge saucepan (one which can go in the oven). Add the drained kidney beans, garlic and bay leaves. Grind in some pepper and a little salt and pour over boiled water so that it covers everything by a couple of centimetres.

Bring to the boil and spoon off any scum which forms. Stir and transfer to the oven (low temperature as for a stew - about 120C if cooking for only 3 hrs or lower if cooking all day)

Leave in the oven for as long as possible. I cook this all day at a really low heat - about 100C.

Remove from the oven and taste - add more salt if needed.
